Lipids
yes they can
Marine arctic animals use their fat stores for buoyancy and insulation. The fat is made into a specialized form called blubber.
Glycogen (made up the macromolecule carbohydrates)
It's something like, uhh, origanates.
warm blooded animals
it gives them macromolecules such as carbs, amino acids
Polymer
If you have a(n) amino acid as a nutrient macromolecules, then everything that has it would be destroyed or killed, including fruits and animals, even people.
Feathers help with pushing air aside (for flying) and in most cases they are also used for insulation.
The enzymes that are in the stomach are what causes polymeric macromolecules to break down into smaller pieces so that the body can use them. These are found within the digestive tract of humans and other animals.
Yes, foods eaten by animals are composed of macromolecules such as proteins, carbohydrates, and lipids, which provide essential nutrients for growth and energy. These macromolecules are broken down during digestion into smaller molecules that can be absorbed and utilized by the animal's body for various biological processes.
You mean " for cold blooded animals". Yes.
